ROTARY Application filed September 1 0 all whom it may concern:

Be it known that I, ALBERT Coon, a citizen of the United States, residing at Holyoke, Massachusetts, have invented certain new and useful Improvements in Rotary Clearers, of which the following is a full, clear, and exact description.

My invention relates to rotary clearers such as are used upon spinning and twisting machines and the like for the purpose of removing lint which is liable to be caught by and twisted into the thread or yarn so as to result in an inferior product, and has for its object to provide a rotary clearer which shall emit air to blow away the lint.

My invention further has for its object to provide a self-contained attachmentwhich can be inserted either in a body portion specially made for it, or in an old rotary clearer of the traveling; type upon making a suitable bore within its core.

The following is a description of two embodiments of my invention, reference being had to the drawings in which:

Figure 1 shows a transverse diagrammatic view of a rotary clearer of the traveling .type lying upon the rolls of a twisting or spinning machine;

Fig. 2 is a plan view of the same:

Fig. 3 is a longitudinal section of a rotary clearer of the traveling type embodying my invention Fig. 4 is a section of the same on the line 4%.; Fig. 3;

Fig. 5 shows broken perspective. views of three vanes removed from the clearer;

Fig. 6 shows a clearer of the nontravelim type with a portion of a similar clearer adjacent thereto, both embodying my invention in conjunction.

Fig. 7 shows a section on the line 7i', Fig. 6;

Fig. 8 shows a section on the. line 8-S, Fig. 7 and Fig. 9 shows a section on the line 9-9. Fig. 6.

Referring more particularly to the drawings. 1 is a core of a rotary clearer of the travelingtype, said core being of the well known mechanical form and when in use restin against the rolls 3 and at. of the spinning and twistinqmachine. I provide this core 1 which is ordinarily of wood. with a bore having a portion 5 adjacent to the smaller end of the cone which is of smaller diameter than the other portion so as to CLEARER.

form a shoulder 6. Against this shoulder rests a spider 7. At the other end of the cone is secured a plate 8. The spider T and plate 8 carry a shaft 9 fixed thereon and are preferably connected by a housing 10 secured thereto so as to form a readily removable self-contained structure. lVithin the housing and mounted upon the shaft 9 are a plurality of vanes, preferably three vanes 11, 12 and 13 having" knuckles which surround the shaft 9, the vanes being so constructed as to tit between the shaft and the internal wall of the housing so as to form partitions which shall be as airtight as is compatible with free movement. The vane 13 in Fig. 3. is shown broken off for the purposes of cleari'iess. illounted on the housinp plate 3 are three projections in the form of pins H. 15 and 16. shown approximately 120 apart. The vane ll is n-ovided with two end grooves ['7 which are spaced away from the axis of the shaft 9 at distances equal to the distai'lces of the pins 15 and 16 from said axis. The vane 12 is provided with two grooves 18 whose radial position corresponds to the radial position of the pins let and 15. while the vane 13 is provided with two grooves '19 whose radial positions correspond with the radial positions of the pins 14- and 16.

The pins and grooves above referred to are made comparatively small so that the grooves will not seriously interfere with th tightness of the 'anes within the chan'iber of the housing.

lVith the clearer as thus constrm-tod. when the clearer revolves in the direction shown by the arrow in Fig. 4. the pin H- will enpage the vane ll so as to lift it to the position shown whereupon it will fall by gravity toward the vane 12. which held by gravity at this time in the downward position as shown. As the vane 11 falls it passes hythe pin '16 on account of one of the .q-rooves l7. and pushing; the air ahead of it forces it out through the lowermost part of the spider 7 so that it is discharged through the lower pa t of the portion 5 of the bore in the core. As it rushes out. it blows away any lint which may he in the path of the blast. producing a decided puff. which is all that is necessary for that purpose- -is the clearer continues to revolve the pin 12 lifts the vane 13 which in time falls toward the vane ll. then in its lower position. passing; by the pin l t on account. of one of the grooves 19:

and in a similar manner the van 12 is lifted by the pin 16 and falls so that with the construction shown, the 'e are three putts of air delivered for each revolution of the clearer.

In the form shown in Figs. 6 to S, the internal construction is the same except that the clearer is made shorter and of cylindrical form and in two connected sections, the ends of each section being provided with a series of discharge holes 20 through which the air is expelled in proximity to the supporting bearings oi the rolls. 2; the putts produced thus blowing away the lint there from. The rolls 2 are of the ordinary form having end bearings and an intermediate bearing for a hook 2i. caraving a weight 22' which holds the same in position. T his hook is provided with an arm 2-3 which surrounds the connection 24 between the two clearer sections and assists in holding the clearer upon the rolls. The clearer in its central portion is preferably covered with felt, as shown at I preferably use the vane type of blowing mechanism for embodying: my invention so as to produce the putts above referred to, but as will be evident to those skilled in the art my invention permits of various moditi ations without departing from the spirit thereof or the scope of the appended claims.

What I claim is:

l. in a rotary clearer, the combination of a clearer body having a passage therein, and means for causing air to be discharged from said passage.

2. In a rotary clearer, the combination of a. clearer body having a passage therein, and means carried by the clearer for causing air to be discharged from said passage.

3. In a rotary clearer, the combination of a. body having a passage therein, and a blowing device adapted to be actuated by the movement of revolution of said body so as to cause air to be discharged from said passage.

at. In a rotary clearer, the combination of a chambered body having internal and external surfaces of revolution and a plurality of vanes mounted to revolve within the chamber of said body about the axis thereof and means on s: id body adapted to engagesaid vanes, respectively, so as to lift them independently and permit them when lifted to fall one at a time so as to force air out of the chamber of said body.
